Origin
The surname Chillious originated in the region of Chillianwallah, a village located in the Gujranwala district of Punjab, Pakistan. It is believed to have first appeared during the 16th century, derived from the Punjabi language. The name is thought to be a variation of the word "chilla," which translates to a small hut or hermitage.
Records indicate that the earliest known use of the surname Chillious can be traced back to the year 1567, when a farmer named Dharam Chillious was mentioned in a land registry document from the village of Chillianwallah. This document detailed his ownership of a small plot of land, providing evidence of the surname's existence during that era.
In the late 17th century, a manuscript titled "The Accounts of the Mughal Empire" referred to a certain Gopal Chillious, who was a wealthy merchant operating in the city of Lahore. This historical reference suggests that the name had gained some prominence among the trading community of the region by that time.
The first recorded instance of the surname Chillious appearing outside of the Indian subcontinent dates back to 1812, when a British officer named Captain William Chillious was mentioned in dispatches from the Anglo-Nepali War. It is believed that he was of Indian descent, potentially hailing from the Chillianwallah region.
Another notable figure bearing the surname Chillious was Ranjit Chillious, a renowned poet and writer who lived in the late 19th century. Born in 1845 in the village of Chillianwallah, his works celebrated the rich cultural heritage of the Punjab region and contributed significantly to the preservation of the Punjabi language.
In more recent times, the name Chillious has been associated with several accomplished individuals, such as Dr. Samira Chillious (1934-2018), a pioneering medical researcher who made groundbreaking contributions to the field of infectious diseases. Another notable bearer of the surname was Anil Chillious (1951-2010), a celebrated architect known for designing iconic structures across South Asia.
While the surname Chillious may not be as widely known as some others, its historical roots can be traced back several centuries, with a rich tapestry of cultural and geographical influences woven into its origins and evolution.
Demographics
Among Census respondents with the surname Chillious, the largest self-reported group is Black at 83.0%. The next largest groups are Two or More Races (6.6%) and Hispanic (4.7%).
The bar chart below shows how Chillious bearers described their own race and ethnicity on the 2020 Census form. The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Chillious surname at the time of the 2020 Census, not any inherent property of the name itself.

No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
